Not every rock band can score a No. 1 at Rock Radio and, in the same breath, take a swing at *NSYNC without so much as breaking a sweat. Then again, Sleep Theory has never been “every rock band.”

The Memphis-bred four-piece — vocalist Cullen Moore, guitarist Daniel Pruitt, bassist Paolo Vergara, and drummer Ben Pruitt — has officially dropped the studio video for their cover of *NSYNC’s turn-of-the-millennium pop juggernaut “Bye Bye Bye.” If you’ve caught them live over the past year, you already know the drill: heads nodding, phones up, and an entire crowd suddenly remembering every word to a song they swore they’d forgotten.

The cover has been a fan-favorite staple of Sleep Theory’s live set, and the studio version captures exactly why it works. Instead of leaning on irony, the band leans in — pairing the song’s undeniable hook with the kind of alt-rock muscle that has made them one of the fastest-rising acts in the genre. It’s a sharp reminder that big pop melodies and heavy guitars aren’t enemies; in the right hands, they’re a cheat code.

That instinct for blurring lines has been Sleep Theory’s calling card since day one. Across their debut EP and their debut album, “Afterglow” — produced by David Cowell and mixed by Zakk Cervini (Bring Me The Horizon, Bad Omens, Architects) — the band has folded R&B phrasing, pop songcraft, and metal-adjacent heft into songs that refuse to pick a lane. The result: 875 million catalog streams, three No. 1s at Rock Radio, and a Best New Rock Artist win at the iHeartRadio Music Awards.

Between a sold-out debut European headline tour and two sold-out North American headline runs, Sleep Theory has spent the last year proving they’re not a moment — they’re a movement. And with a summer packed full of European festival stops (Graspop, Pinkpop, Vainstream, Impericon) rolling straight into a monster U.S. run — Inkcarceration, Warped Tour Montreal and Mexico City, Louder Than Life, Aftershock, and Sick New World among them — that momentum isn’t slowing down anytime soon.

If “Bye Bye Bye” is any indication, Sleep Theory aren’t just here to play the rock game — they’re rewriting the rulebook one unexpected swing at a time. Hit play, turn it up, and catch them on the road while you still can.
